3 Quick Installation

This chapter describes how to configure the WAN network interfaces on Arctic3G.

3.1 Connection Principle

Arctic 3G has three network interfaces, Ethenet WAN, Mobile WAN (3G) andEthernet LAN. WAN interfaces are used for connecting Arctic 3G to publicInternet or private APN. Ethernet LAN is used for connecting other Ethernetdevices to Arctic 3G's local network.

WAN interfaces can be configured to get redundant system where one WANautomatically gets traffic if the other one goes down. For example, if theEthernet LAN goes down, the traffic will be automatically switched to mobile3G and back when the Ethernet interface comes up again. This way theavailability of the remote system will be better than with just one interface.

3.2 Connecting cables

1. Verify that the power switch is in the OFF position.

2. Connect the Ethernet cable between Arctic 3G (Ethernet LAN connector)and your configuration computer.

3. Connect power supply to Arctic 3G and toggle power the switch to ONposition.

4. The error LED should turn on immediately after the power switch turnedon.

5. After the system has initialized, the Error LED turns off and the RUN LEDstarts to blink.

3.3 Logging in to Arctic 3G

This section describes how to log in to Arctic 3G using web configurationmenu.



1. Configure your computer to use the same IP address space than Arctic 3G(laptop IP for example 10.10.10.11 with netmask 255.0.0.0). Check withping command.

2. Connect to the Arctic 3G using your web browser. The default IP addressof Arctic 3G is 10.10.10.10 (netmask 255.0.0.0). Note that you have toconnect to a HTTPS port (see figure 13).

Figure 10. Browser https example

3. Your browser may mention about certificates, you can safely ignore themat this point.



4. When you get to the login screen, enter username and password andpress Login button. The actual screen depends on the used web browser.

Note!Default username is viola-adm and default password is violam2m. It isrecommended that the default password is changed before the product isconnected to a public network.

5. Now you should be logged in. White texts on the blue background onthe left are the primary navigation texts and they are always visible onthe screen. Individual screens may have their own tabs which split theconfiguration fields on larger screens. See figure 14.

Figure 11. Configuration menu

3.4 Configuring Ethernet LAN

1. Select Network->Ethernet LAN from the left menu.

2. Enter your preferred configuration to the configuration fields.

3. Press Submit button on the bottom to save the settings.



4. Select Tools->Reboot from the left menu and press Reboot button torestart the unit

Note!If you change the IP addresses, your existing web browser connection hangsup after you apply the settings, so open a new connection to the new IPaddress (check your Ethernet cabling)

5. Now you should be able to connect to the Arctic 3G with your new IPaddress.

3.5 Configuring Mobile WAN (3G)

1. Select Network->Mobile WAN (3G) from the left menu.

2. Enter your preferred configuration to the configuration fields.


3.6 Configuring default gateway

1. Select Network->WAN Failover from the left menu.

2. Set "WAN Default Route"="Yes". This has to be enabled to use eitherWAN as default route interface.

3. If you want to use 3G as default gateway, set "Primary WANInterface"="Mobile WAN (3G)".

4. If you want to use EthernetWAN as default gateway, set "PrimaryWANInterface"="EthernetWAN".

5. If you have both Ethernet WAN and Mobile WAN configured, you candefine the Backup WAN Interface. If the primary WAN interface comesdown, Arctic 3G automatically switches default route to backup WANinterface. Figure 15 shows example configuration where Ethernet WAN isconfigured as default route.

Figure 12. Ethernet WAN default route example


7. Select Tools->Reboot from the left menu and press Reboot button torestart the unit.

4.1.2 Ethernet WAN

This screen configures the Ethernet WAN interface on Arctic 3G.

Figure 15. Ethernet WAN configuration

Connectivity Monitor settings are used whenWAN redundancy functionalityis wanted. Monitor keeps checking the connection to given remote host todetermine the network status. If the ping does not get an answer for given timewindow, it informs the WAN switch logic to try the secondary interface.

If the WAN redundancy is implemented by using two separated Ethernetconnections with different gateways, the Backup Gateway parameter needs tobe configured towards correct backup gateway. Backup Gateway parameter isnot needed if WAN redundancy is implemented with wireless connection.

See section 4.1.4 for more details about WAN redundancy.

4.1.3 Mobile WAN (3G)

This screen configures the Mobile WAN (3G) interface on Arctic 3G.

5 Serial Port Configuration

5.1 Configuring serial gateway

This section describes how to configure serial <-> Ethernet functionality.

Serial gateway feature enables data from the serial port attached device to berouted to Ethernet and vice versa. Serial gateway processes the transmitteddata transparently and does not alter it any way except for buffering it fortransmission. Because of the transparent communication, any protocols canbe used in actual communication between nodes.

Figure 22. Serial gateway configuration screen

Serial gateway configuration depends on used protocols.

Both serial ports have their own configuration screens, located inApplications->Serial Gateway (RS1) and Applications->Serial Gateway(RS2).
